Free reeds

Concertina

A small hexagonal or square bellows-driven free-reed instrument with buttons on both ends. English, Anglo and duet systems are the main families; the bandoneon and Chemnitzer are related larger instruments. Covers the English (treble) and Anglo here; the bandoneon has its own entry.1

Part of the Free reeds family; that family's advice shows here too.

The 5 setups behind this: placement and quotes
  • Distant Rode NT4
    stereo, some way back from the instrument
    My favourite mic for the job is a Rode NT4, a stereo condenser that gives stereo without worrying about the ends.2
  • Close flat (boundary) condenser, 1 or 2 for stereo, 12-18 in out front
    close, front
    For recording, place a flat condenser mic (or two for stereo) about 12-18 inches out front.3
  • Close 2 × Neumann KM 84 or Oktava MK-012
    pair, crossed, ~2 ft in front
    My best results have come when I miked the instrument from the front with a pair of microphones, usually Neumann KM 84s or Oktava MK-012s. ... A pair of microphones, usually Neumann KM 84s or Oktava MK-012s, ideally a crossed pair a couple of feet away.4
  • Close 2 × pair of mics about 9 in apart, both pointing forward (Alistair Anderson)
    pair, spaced, close
    Alistair Anderson favors a pair of mics spaced about 9 in apart, both pointing forward.4
  • Close Shure SM81 or Neumann U 87
    single mic, ~10 in in front of centre
    A single condenser mic (usually an SM81 or U 87) about 10 in in front of the center of the instrument.4

  • Clip-on Microvox concertina clip-on system
    clip-on, one per end
    Two close mics which you attach one to each end of the concertina using Velcro; one lead runs to the DI box.2
  • Clip-on Neumann MCM KK 14
    clip-on, stage (FolkBaltica 2022)
    Concertina was among the instruments fitted with Neumann clip mics in the festival's opening-concert test (paraphrase).5
  • Clip-on mini omni mics taped on the tone holes at each end, or on each wrist
    clip-on, both ends (PA)
    For PA, tape a mini omni mic onto the tone holes on each side (two mics total).3
  • Close Free reeds advice cardioid dynamic pointed at the middle of the instrument from about 8 in
    close, live dance
    Sax, clarinet, bagpipes, accordion, concertina: point a mic at their middle from about 8 inches away and they should sound ok.6

Range

G3 to C71,7196 Hz – 2.09 kHz

Standard 48-key English (treble) concertina: 'from G below middle C to C 3 octaves above middle C' (concertina FAQ); note names are my conversion. 56-key models add 8 keys at the top. (earlier: English treble concertina; the top is 'two octaves or more above the treble clef')

The sound

Air from the bellows crosses reeds; the English and duet are unisonoric (a button gives the same note pulling or pushing), the Anglo is bisonoric (two notes per button).1

Where the sound goes

Sound leaves from both ends, and the ends move. Stamler adds that the melody may jump from one end to the other (Anglo and duet layouts put higher notes on the right and lower on the left). Kaufman: point a cardioid dynamic at the middle from about 8 in for live dance sound.2,4,1,6

Recording it

On stage

One mic at the middle of the bellows is the usual and weak method; two mics, one per end, are better but feel limiting. Microvox sells a pair of small mics that stick on each end with Velcro and join into one belt box and DI. Bartlett: mini omnis taped to the tone-hole areas on each side, or on each wrist. Internal mics fitted by a player to an Anglo are said to work, but one maker (Colin Dipper) thought permanent internal mics would harm the sound. Consider no mic at all in small venues. Neumann's MCM KK 14 clip mic was tried on a concertina at the 2022 FolkBaltica festival (a manufacturer's test report, no detail on the concertina).2,3,5

Problems to watch

The moving ends change the level and pan position; a close pair makes the image dart; leakage and a singing player make a crossed pair at two feet difficult.4

About the range

The standard English (treble) concertina is similar to a violin: from the G below the treble clef (G3) to two octaves or more above the clef. The Anglo of about 20 keys is two rows pitched a fifth apart (C/G or G/D) and is not fully chromatic, with notes missing especially at the low end; no figure for a 30-key range was found in a page I opened. Baritone (one octave lower), bass (two lower) and piccolo (one higher) versions exist.1
